Hi,

I have struggled with this a great deal today, using gcc -m64.  My first
error was configuration of milter-greylist:

checking for smfi_register in -lmilter... no
checking for smfi_register in -lmilter -lsm... no
checking for smfi_register in -lmilter -lsmutil... no
Required libmilter not found. Use --with-libmilter

This was something I did not get with 32 bit.  I found an old version
of libmilter in /usr/lib, and realized (a) libmilter was out-of-date
relative to sendmail, (b) it had been built with cc, not gcc, and (c)
it was a 32-bit library.  So I went back to my sendmail code and 
realized that libmilter does not automatically get built and installed
with sendmail.

So I tried to build a 64-bit gcc shared library version of libmilter
for use here.  The URL:

http://www.technoids.org/libmilter.so.html#Appendix

gave me a general approach on how to tackle this.  I'm to the point
where the .c files for libmilter compile just fine, but the shared
library won't link:

gcc -O2 -I. -I../../sendmail   -I../../include  -I/opt/BerkeleyDB/include -I/opt/sasl/include/sasl -I/opt/openssl/include -I/usr/local/include -DSOLARIS=21000 -DNETINET6 -UNIS -UNISPLUS -DNEWDB -DSASL=2 -DSTARTTLS -DSM_CONF_LDAP_MEMFREE -DTCPWRAPPERS -DHASURANDOMDEV -DIDENTPROTO=0 -DDSN=0 -DNOT_SENDMAIL -Dsm_snprintf=snprintf -m64 -g -D_REENTRANT -DXP_MT  -c  strl.c
gcc -lpthread -Wl,"-64" -G -o libmilter.so -h libmilter.so. main.o engine.o listener.o worker.o handler.o comm.o smfi.o signal.o sm_gethost.o monitor.o errstring.o strl.o 
ld: fatal: file /usr/local/lib/gcc/sparc-sun-solaris2.10/4.2.0/crt1.o: wrong ELF class: ELFCLASS32
ld: fatal: File processing errors. No output written to libmilter.so

or:

gcc -lpthread -G -o libmilter.so -h libmilter.so. main.o engine.o listener.o worker.o handler.o comm.o smfi.o signal.o sm_gethost.o monitor.o errstring.o strl.o 
ld: fatal: file main.o: wrong ELF class: ELFCLASS64
ld: fatal: File processing errors. No output written to libmilter.so

Obviously, I'm mixing 32 and 64 bit binaries here but I don't know
why (nor how to fix it with loader options).  I googled on "wrong
ELF class" but didn't find an answer...

Visions of Will Farrell in his Elf outfit come to mind here.  :)

Any help here?
